SNOWPLOW.

Specification of Letters Patent.

Patented Nov. 16, 1920.

of the invention, such as will enable others skilled in the art,to whichit appertains' to make and use the same.

This invention relates to new and useful improvements in snow plows andhas for one of its objects the provision of a device of this characterwhich can be easily and con-' veniently applied to an automobile, truck,or motor vehicle so that roadways can be quickly cleared of snow ofconsiderable depth and which devices can be easily removed when desiredand will not interfere with the cranking or starting of the automobileor truck when a lied thereto,

Another object of t is invention is the provision of an inclined moldboard supported in spaced relation to theground at its forward end byrunners which are adapted to act as knives in cutting the snow intostrips as the snowengages the mold board so as to prevent thesnow frombanking or packing against the mold board, thus requiring less power toshove the device for- Ward. o I

A further object of this invention is the provision of a snow plow ofthe above stated character, which shall belsimple,. durable andefficient, and which may be'manufactured and sold at a comparatively lowcost. With these and other objects in view as y will become moreapparent as the description proceeds; the invention consists in cerq tamnovel features of 'construct1on,comb1- nation and arrangement of partsas will be hereinafter more fully described and claimed.

For a complete understanding of my invention, reference is to. be had tothe following description, and accompanying drawin s in which lgure 11sa SldG'GlGVfiI lOIl-Of a snow plow constructed in accordance with myinvention and illustrating it attached to a motor vehicle, Fig. 2 is afront elevationof the same, Fig. 3 is a transverse sectional viewillustrating the shape of the mold board,

Fig. 4 is a longitudinal sectional view illustrating the means ofsecuring the snow plow to the motor vehicle, Flg. 5 is a bottom planview of the device. Referring in detail to the drawingsQthe numeralindicates as. an entirety a snow plow consisting of a mold board .2, theforward edge of which is disposed straight to form a cutting edge 3.Theniold board 2 is provided with an offset portion 4 that is ofsubstant ally V-shape in cross section arid d verges from its forwardend in the direct1on of 1ts rear end to form inclined faces15 borderedby marginal flanges 6 so that snow engaged by the'cutting edge 3 isdeflected laterally 1n each direction by the inclined faces 5 and setoff of the mold board to each side of the roadway by the marginalflanges 6. The rear edgeof the offset portion 4 of the mold boardslightly curves as illustrated at l to a d v1n deflecting thesnowlaterally in each d1rection.

.8 are secured to the bottom face of themold board 2 and extendforwardly of the out ting edge 3 and have their forward ends curvedupwardly in arcuate-shape to form cutting kn ves 9 that are connectedtogether by a rod 10 on which is positioned-spacing collars 11 so asto'hold the knives in their proper relat1on. The intermediate runner isdisposed within theofi'set portion 4 of the mold board 2 so as tostrengthen and reinforce the same. 1'

A palr of supporting rods 14 and 15 are secured to the under face of themold board 2 and extend beyond the rear edge thereof and are connected.together by a brac 16. The -supporting rod 14 has one end disposed atright angles to form an attaching or Journalmg arm 17 that is-disposedwithin one end of the sleeve 18. The sleeve 18 is' .secured'to theforward end of a power driven 'arm15 and is heldinalinement. therewithb" a fastening element 25. The fastening elbment 25 may-be-slid OR ofthe member 15 so; as to permit the arm 22 to be swung on its pivot fordisengaging the right angled end thereof from the sleeve 18 whendesirint disconnect the device from the'vehicle.

From the foregoing description take in connection with the accompanyingdrawings, 1t will be noted that the plow is supported in an inclined{position forwardly of the motor driven vehicle so that on the plowbeing shoved forwardly by the vehicle, the

Snow will be cut into strips by the knives and passed onto the moldboard,2 whence it is deflected laterally in each direction of theroadway. The rear end of the mold board terminates substantially in aplane with the upper end of the radiator of the motor vehicle so as topermit the device to be used in comparatively deep snow. It will also benoted that the cutting edge 3 of the mold board is supported in spacedrelation to the ground so that stones and other obstructions may passunder the cutting edge without affecting the device.

While I have shown and described the referred embodiment of myinvention, it will be understood that minor changes in construction,combination, and arrangement of. parts may be made without departingfrom the spirit and scope of the invention as claimed.

Having thus described my invention, what claim is 1. A snow plowcomprising a mold board, supporting members secured to the mold board, aright angled extension formed upon the end of oneof the supportlngmembers, an arm pivoted to the other supporting member and having aright angled end, a sleeve receiving the right angled ends and securedto a motor vehicle, mean holding the arm against pivotal movement on oneof said supporting members; and means supporting the mold board at itsforward edge in spaced relation to the ground and adapted to cut snowinto strips.

2. A snow plow comprising a body having its forward edge disposedstraight to form a cutting edge, said body being curved to form an ffsetportion of substantially V-Shape in cross sectlon and having marginaldeflectin flange t its sideedges, said V-shaped o set portion divergingfrom the cutting edge in the direction of the rear edge of said body,means securing the body to a vehicle, and runners secured to said body.

3. A snow plow comprising a body having its forward edge disposedstraight to form a cutting edge, said body being curved to form anofi'set portion of substantially V- shape in cross section and havinmarginal deflecting flanges at its side e ges, said V-shaped offsetportion diverging from the cutting edge in the direction of the rearedge of said body, means securing the body to a vehicle and spacedstrips secured to the offset portion and projecting forwardly of thecutting edge and curved upwardly to form comblned knlves and runners tosaid body.

In testimony whereof I aflix my signature in presence of two witnesses.
